As far as siege weapons go, the actual concern is how historically accurate the weapons are.

We did have a working scenario editor for the game running at one point in time, but a lot of the game's internals have changed since then, so it will need some updating for it to work again, but it will probably make it into the final game. This isn't a map editor, though; it's just for placing units on a map so you can play through your own scenario.

We've talked about releasing a map editor, but if we ever release a map editor, it certainly won't be out when the game is initially released; our internal map editor is way too buggy to be released to the public >:)

As far as when you can play the game, well, we will be doing a beta test some time before the game is released (if you were part of the compatibility test, you'll automatically be included), but I can't be too specific, other than saying sometime this year.

Well, you could have multi-player battles in which players would go head to head in a purely strategic sense. That way its the player's strategy in turning a loosing scenario into a winning one. If you limit it to single battles, it would work. (of course, allowing campaigns between players played across several games would be something new) It would be similar to other strategy games, but without builds, and a fixed starting point in terms of troops and positions. Different scenarios can have either team start at an advantage/disadvantage or an even stage. Extending this further, one can have scenarios based on defensive/siege elements.

We have discussed multi-player, but we don't want to do a half-hearted job. To do it right would take a lot of time, and it would probably be a very different game, so if we add multi-player to Hegemony, it will probably either be an expansion or a separate game.

Personally, I would rather see multiplayer released in a later game using the same base engine as this. The only multiplayer I can see working on this engine, without including a map editor or at least a large selections of non-realistic maps to go with real ones, is a cooperative campaign in which one player starts with the part of the starting province the single-player would get, and the other gets the other side in the same way. Thus, players would be working as generals under Philip, even though that isn't exactly historically accurate, thus ruining the effect of the game to begin with.
